Global 107 Silicone Rubber Market Strategic Research Report

Scope of the Report

The global 107 Silicone Rubber market size is predicted to grow from US$ 1,397 million in 2025 to US$ 2,036 million in 2032; it is expected to grow at a CAGR of 5.0% from 2026 to 2032.

In 2025, global sales of 107 Silicone Rubber reached approximately 690 k tons, with an average market price of about USD 2,070 ton, an annual production capacity of roughly 750 k tons, and an industry-average gross margin of approximately 32%.

107 Silicone Rubber refers to hydroxyl-terminated polydimethylsiloxane, also known as silanol-terminated PDMS or OH polymer, supplied as a transparent or semi-transparent silicone fluid or high-viscosity base polymer across different viscosity grades. Its molecular backbone consists of Si-O-Si bonds, while the terminal hydroxyl or silanol groups enable condensation curing in the presence of crosslinkers, catalysts and fillers. The material is primarily used as a base polymer or reactive intermediate for room-temperature-vulcanizing silicone systems, including RTV sealants, mold-making silicones, electronic potting compounds, adhesives, coatings, filler treatment systems and other industrial silicone formulations. The scope of this study focuses on industrial and commercially supplied OH-PDMS products used as functional silicone base polymers.

Based on our research, 107 Silicone Rubber should be treated as a silicone base polymer rather than a downstream finished sealant. Its technical core is hydroxyl-terminated PDMS, also described internationally as silanol-terminated PDMS, OH polymer or α,ω-dihydroxypolydimethylsiloxane. The product sits between upstream silicone monomers and siloxane intermediates on one side, and downstream RTV sealants, mold-making silicones, electronic potting compounds, adhesives and coatings on the other. A narrow market scope is therefore necessary: broad silicone rubber, finished RTV sealants and general silicone oils would materially overstate the addressable market. Under the narrow scope, the market is smaller but more analytically useful, because it captures the real base polymer supply pool and avoids double counting downstream compounders and distributors.

From a supply perspective, the global industry is structured around three groups: large multinational silicone producers, Chinese integrated silicone companies, and regional or specialty polymer suppliers. Multinational producers remain strong in high-purity, high-consistency and application-specific OH-PDMS grades, supported by global customer relationships and formulation expertise. Chinese producers have become increasingly important in bulk RTV-107 and hydroxyl silicone oil supply, benefiting from integrated access to DMC, siloxane intermediates and downstream silicone markets. North America and Europe also host several specialty suppliers focused on customized, high-value or smaller-volume applications. The gap between the broad longlist and the core formal list is mainly driven by the presence of trading companies, export brands, downstream compounders and regional suppliers with incomplete manufacturing evidence.

Demand remains anchored by construction sealants, but growth is gradually shifting toward electronics, electrical insulation, photovoltaic and renewable-energy materials, industrial bonding, mold-making and specialty coatings. Construction-related demand is cyclical and price-sensitive, which increases volatility in bulk RTV-107 grades. Electronics, automotive, energy and industrial applications place higher emphasis on low volatility, batch consistency, curing behavior, electrical reliability and long-term durability, supporting a more resilient demand base for higher-quality OH-PDMS products. As end markets tighten requirements for weatherability, low VOCs, durability and electrical safety, hydroxyl-terminated PDMS should maintain a stable role in silicone formulation systems, even though commodity grades will remain exposed to oversupply and price competition.

From a technology and product evolution perspective, the industry is not moving away from RTV-107 silicone rubber entirely; rather, it is improving viscosity control, molecular weight distribution, volatile content, terminal group stability, low-cyclic content and application-specific formulation compatibility. Leading producers are increasingly focused on high-purity and specialty grades for electronics, industrial and high-performance sealant applications, while regional suppliers compete more heavily in standard viscosity grades for mass-market sealants and industrial formulations. Future competition will therefore become more polarized: integrated producers with upstream cost control and strong quality systems will gain resilience, while small commodity-focused producers may face margin pressure during silicone downcycles.

From a policy and industry dynamics perspective, environmental regulation, chemical park management, energy consumption controls, low-VOC building material policies, electronics localization and renewable-energy investment will continue to influence the RTV-107 silicone rubber value chain. China’s silicone capacity expansion has increased global supply flexibility but also intensified cyclicality in lower-end products. At the same time, international producers are using portfolio optimization, M&A and regional supply-chain restructuring to strengthen their positions in higher-value silicone materials. For 2026–2032, the market is expected to grow at a moderate pace, with revenue CAGR estimated at approximately 4.80%, driven by volume expansion in Asia and specialty demand growth, while pricing remains sensitive to DMC cycles and capacity utilization.
